Several factors that may predict patient prognosis, have been identified, including (1) Breast cancer subtypes: AMD1 expression is especially upregulated in BLBC; (2) Tumor grade: high AMD1 expression is correlated with higher tumor grade; (4) tumor metastasis: high AMD1 expression has a much higher probability of distant metastasis and metastatic dissemination to the brain and lungs that is line with the metastatic propensity of BLBC; (3) Survival rate: high AMD1 expression predicts poorer survival in breast cancer patients. The gene discussed is AMD1; the disease is neoplasm.
